Embodiment 1

[0030] 20 / 22D autumn cocoon raw silk is reeled, the reeling speed is 80 m / min, and the average number of cocoon grains is 7.8. The thread after passing through the thread collector 1, after passing through the lower guide hook 3, passes through the thread guide ring 5 on the top of the rocker, relying on the angle θ (30°) between the thread and the axis to make the thread close to the height 10cm, diameter is 8 centimetres, and outer wall surface material is the class twist disc 7 of polyurethane rubber, does 45 ° of fan motion, and the speed of fan motion is 120 times / min, and the silk strip after doing fan motion enters upper guide wire hook 4, Complete the effect similar to silk sheath. reeling small For silk flakes, the moisture regain of doffing is 14.2%, the cohesion of the reeled raw silk is 106 times, the cleanness is 94 points, and the cleanness is 98.5 points.

Embodiment 2

[0032] 27 / 29D spring cocoon raw silk is reeled, the reeling speed is 75 m / min, and the average number of cocoon grains is 9.6. The thread after passing through the thread collector 1, after passing through the lower guide hook 3, passes through the thread guide ring 5 on the top of the rocker, relying on the angle θ (15°) between the thread and the axis to make the thread close Paste height 5cm, diameter is 5 centimeters outer wall surface material is the quasi-twist plate 7 of silicon rubber, does 90 ° of fan motion, and the speed of fan motion is 90 times / min, and the silk strip after doing fan motion enters upper guide wire hook 4 , to complete the work similar to the silk sheath. reeling small For silk flakes, the moisture regain of doffing is 16.5%, the cohesion of raw silk is 110 times, the cleanness is 93.5 points, and the cleanness is 98 points.

Embodiment 3

[0034] 40 / 44D spring cocoon raw silk is reeled, the reeling speed is 70 m / min, and the average number of cocoon grains is 14.2. The thread after passing through the thread collector 1, after passing through the lower guide hook 3, passes through the thread guide ring 5 on the top of the rocker, relying on the angle θ (35°) between the thread and the axis to make the thread close to the height 10cm, diameter is 8 centimetres, and outer wall surface material is the quasi-twist plate 7 of silicon dioxide / polyurethane composite material, does 120 ° fan motion, and the speed of fan motion is 30 times / min, and the silk strip after doing fan motion enters upper Guide wire hook 4, finishes twisting sheath work. reeling small For silk flakes, the moisture regain of doffing is 16.5%, the cohesion of raw silk is 105 times, the cleanness is 94 points, and the cleanness is 97 points.

Abstract

The invention discloses a device and a method for replacing croisures. A motor is adopted to drive a driving disc to rotate at high speed through a rotating rod, and to drive a silk guide ring fixed at one end of a rocking rod to swing through the effects of a connecting rod and the rocking rod. Strand silk enters a lower silk guide hook through a filament collection device, then clings to a quasi-twisting disk penetrates through the silk guide ring fixed at one end of the rocking rod in a way clinging to a similar entwisting disc, performs reciprocating sector movement with the silk guide ring, and accomplishes the effect similar to the effects of the croisures, so that manual sheath entwisting operation and croisures are canceled during the reeling process, reeling without the croisures is realized, and the labor productivity and the raw silk quality are improved.

Description

technical field [0001] The invention relates to a silk reeling device and method, in particular to a mechanical twisting device and method for replacing silk sheaths. Background technique [0002] In the silk reeling process, after the threads of the cocoons in the silk reeling pass through the thread collector, they cannot be directly wound on the small superior. Because the cocoon filaments are loosely bonded to each other and cannot be tightly entangled, such filaments are weak in strength and easily split. The silk thread contains a lot of water. If it is directly wound and formed, it will not only be difficult to dry and affect the color of the silk, but also will make the sericin stick to each other to form a hard rubber thread sheet. Therefore, in the silk reeling process, it is necessary to manually twist the sheath to form a silk sheath. [0003] The cocoon silk group in silk reeling has initially formed raw silk through the rotary core and thread collector. Ho...
